Bosch K Jetronic system and control pressures

Post#1 » Thu Nov 14, 2019 8:09 pm

I got an S & K tool to measure the control and system pressures of the CIS K-Jetronic injection on my 280GE but I cannot find what pressures are correct.
Does anyone know what the factory control and system pressures should be?

I have a pretty extensive manual from Bosch for the K-Jetronic system. Could send it to you in an email. I’m away from computers and can’t upload PDF:s on here unfortunately.

I have in my notes that the system pressure of 4 cyl engines should be 5,3 to 5,5 bar, 6 cyl engins 5,7 to 5,9 bar
Here is the link to some useful resources...

Thanks Baddy and Cal.
I forgot to note that I have a European engine without Lambda - just straight K-Jetronic mechanical.
